JOHN J. MALLOY, OF PORTLAND, OREGON, ASSIGNOR TO THE PACIFIC GAR COUPLING COMPANY, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 593,183, dated November 2, 1897.

Application filed February 1, 1897. Serial No. 621,535. (No model.)

To to whom it may concern.-

Be it known that I, JOHN J. MALLOY, a citizen of the United States, residing at Portland,-

ney or knuckle type, and has for its object.

the improvement of the locking mechanism for securing the knuckle when cars have been coupled together, such improvement consistingin simplifying the locking mechanism without detracting from the strength of the draw-head, and I have further provided the draw-head with a device for holding the same in case of becoming broken and prevent it from falling on the track.

These improvements I have illustrated in the accompanying drawings, in which Figure l is a plan of my coupler, and Fig. 2 is a transverse vertical section on the broken vertical line of Fig. 1.

The letters designate the parts referred to.

The draw-head a is provided with an I;- shaped knuckle Z) of about the usual type, and the inner side of the arm 0 of the knuckle b and the wall of the left arm d of the drawhead are adapted to operate together, as illus trated in Fig. 2-tl1at is to say, the said wall (I being so constructed as to partly receive the arm 0, which is itself adapted to be so received. The object which I had in view in this arrangement was to adapt my coupler as nearly as possible to the standard type, consistent with the working principle of my invention, without weakening the draw-head or its cooperating parts. At the top of the arm 0 I have provided a block or elevation e, on which I have pivotally mounted the hook f, a portion of the wall (Z being cut away to receive such elevated part c. The hook f has on its upper side a rib g with an eye it, the former to strengthen the said hook and the latter for lifting the same. To enable the hook to act automatically when the arm a of the knuckle is brought in contact with the arm (1 of the draw-head, I have provided an inclined approach 2', upon which the tip of the hook f slides until it drops into the verticallyextended opening 3', and by so doing locks the knuckle.

To uncoup1e,I have provided the rod Zaheld in staples Z m on the exterior of the drawhead, a stop at holding such rod in its proper place and the bent-up part of such rod 70 entering the opening j and abutting against the tip of the hook f, which it lifts when the rod 79 is drawn up.

0 is a horizontallyprojecting arm whereby the end of the draw-head will be supported should it accidentally be broken off while the train is in motion.

. ing vertically therethrough, a knuckle pivoted in said draw-head having a rearwardlyextending arm, a hook vertically pivoted on said arm, means for automatically lifting the hook when coupling to drop it into said aperture, and a push-rod extending upward into said vertical aperture for raising the hook therefrom to 'uncouple the draw-head, substantially as described.

In witness whereof I have hereunto set my signature in the presence of two witnesses.

JOHN J. MALLOY.
